How to get fragmented url value in javascript?

There are multiple ways we can retrieve fragmented url values

• use window.location.hash property

window.location.hash property returns the fragmented value

if the page url is abc.com/about#contact

console.log(window.location.hash) //returns  #contact value

if the page url is abc.com/about

console.log(window.location.hash) //returns empty value

• using string url

if url contains a string url, use the substring() method

var strUrl = "www.abc.com/about#contact";
var hash = strUrl.substring(strUrl.indexOf('#')+1);
console.log(hash); // returns contact

Another way using url object

var url = new URL('https://abc.com/about#contact');
console.log(url.hash); // returns #contact

• using split function

Split the string using the separator(#) symbol and returns the second element from an array using index=1.

let strUrl = "www.abc.com/about#contact";
let fragmentValue=strUrl.split('#')[1]
console.log(fragmentValue);
